Comparison Between The Trap Bar Dead Lift And Back Squat Exercises On Vertical Jump, Douglas A. Young

Theses and Dissertations

The ability to produce power during competition is essential. Football requires explosive power in order to get off the ball faster, increase speed of the first step, and increase the height of the vertical jump. Most strength training professionals use the back squat to increase power of the lower extremities; however, as large forces are placed on the back, athletes are at greater risk for injury. The trap bar dead lift is similar to the back squat in movement and form, but the trap bar dead lift reduces the force on the lower back. After testing for maximum vertical jump,athletes …

Acute Arginine Supplementation Fails To Improve Muscle Endurance Or Affect Blood Pressure Responses To Resistance Training, Beau K. Greer, Brett T. Jones

All PTHMS Faculty Publications

Dietary supplement companies claim that arginine supplements acutely enhance skeletal muscular endurance. The purpose of this study was to determine whether acute arginine a-ketoglutarate supplementation (AAKG) will affect local muscle endurance of the arm and shoulder girdle or the blood pressure (BP) response to anaerobic exercise. Twelve trained college-aged men (22.6 +/- 3.8 years) performed 2 trials of exercise separated by at least 1 week. At 4 hours before, and 30 minutes before exercise, a serving of an AAKG supplement (3,700 mg arginine alpha-ketoglutarate per serving) or placebo was administered. Resting BP was assessed pre-exercise after 16 minutes of seated …

Plantar Pressure Distribution Differences In Physically Active Individuals With And Without Functional Ankle Instability During A Side Cut, J'Nai Pittman

Human Movement Studies & Special Education Theses & Dissertations

Context: Functional ankle instability (FAI) is a popular condition in the physically active population. There is a surplus of evidence to demonstrate how FAI decreases proprioception, balance, and overall athletic performance. However, to date there is no evidence that demonstrates how F AI correlates to alterations in plantar pressure distribution differences in a physically active population while completing athletic tasks. Objective: To assess differences in plantar pressure distributions while completing a side cut in individuals with and without FAI. Design: Observational case-control. Setting: Outdoor field turf and research laboratory. Participants: Fifty ankles from physically active individuals (FAI: age= 21.47±3.02 yrs; …

The purpose of this investigation was to examine the potential effects of SR2W-1 supplementation on cycling performance, central fatigue, and a variety of physiological parameters, including blood lactate, blood pH, heart rate (HR), rating of perceived exertion (RPE), oxygen consumption (VO2), expired ventilation (VE), and respiratory exchange ratio (RER). Methods: Five recreational cyclists (38 ± 8 yr, 168.4 ± 4.3 cm, 68.8 ± 5.6 kg, and 54.4 ± 2.6 mL/kg/min) performed 20-min of steady-state cycling (~85% VO2max) followed by three 1-min high intensity intervals at VO2max with 30-sec active recovery periods at 100 W, 15-min passive recovery period, and a …

Agonist And Stabilizer Muscle Activity During A Push Up On Unstable Surfaces, Anthony J. Dyrek

UNLV Theses, Dissertations, Professional Papers, and Capstones

A recent trend among fitness professionals is to have clients perform resistance exercises on unstable equipment. Anecdotally, this is done with the intent that stabilizing and agonist muscles are more active while doing certain exercises on unstable surfaces. However, there are limited data as to whether or not this is the case and no studies have investigated muscle activity while doing the same exercise on surfaces that offer different levels of stability. Therefore, the purpose of this study is to measure electromyography (EMG) during push up exercise performed on unstable surfaces as well as on the ground. Surface EMG was …

The Acute Effects Of Static Stretching Of The Gastrocnemius On Limits Of Stability In Young Adults Versus Elderly Adults, Matt Bugnet, Kirk Player

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Balance is an important part of everyday life for all individuals with many body systems interacting to achieve optimal balance. Proprioceptive organs aid in this interaction, while also acting as stretch receptors. Therefore, it is possible that stretching may influence the overall balance of the individual. The purpose of this study was to investigate the acute effects of stretching on dynamic balance of healthy young and elderly adults. The two groups were used to determine if stretching may discriminately affect balance at different ages.

Subjects: Thirty healthy adults between the ages of 18 and 35 …

Self-Reported Exercise And Risk Of Osteoporosis In Prostate Cancer Patients Receiving Androgen Deprivation Therapy, Lori J. Mennen-Winchell

Loma Linda University Electronic Theses, Dissertations & Projects

Prostate cancer is stimulated to grow in response to testosterone. Androgen deprivation therapy (ADT) leads to chemical castration and suppression of prostate cancer cell production. Testosterone levels less then 300ng/ml decreases bone mineral density and could result in osteoporosis. Studies have shown that during the first year of ADT, fracture risk, mainly in hips and spine increases about 50%. In men, 40% of hip fractures result in death. Exercise may reduce the risk of osteoporosis and thus contribute to the prevention of hip and other fractures. There is limited data regarding whether exercise is associated with a reduced risk of …

Thirty-one male participants between the ages of nine and fourteen were recruited and …

The Comparison Of Hamstring/Quadriceps Strength Ratio In The Dominant Versus The Non-Dominant Leg Of Elite Female Artistic Gymnasts, Marina Moure

Human Movement Studies & Special Education Theses & Dissertations

The majority of the injuries in women's artistic gymnastics occur in the lower limbs (Marshall et al, 2007). Hamstring muscle strains are prevalent in sports that involve sprinting (Ekstrand & Quillist, 1985; Orchard, 2001; Croisier et al., 2008) with a high reinjury ratio (Orchard, 1993; Orchard, 1997). Recent studies have linked an increase of muscle injury rate in the lower limbs to strength muscle imbalance between legs and the relation between the hamstring and quadriceps strength (Croisier et al., 2002; Yamamoto, 2008; Sugiura et al, 2008). In order to determine if there is an imbalance in women's artistic gymnastics, forty-three …
